The Communications Manager LAN device driver must be loaded before:

TRNETDD.SYS - IBM Token-Ring device driver
PCNETDD.SYS - IBM PC Network device driver
ETHERDD.SYS - IBM ETHERAND device driver

The device driver provides services for MAC frame protocols.

DEVICE=x:\CMLIB\LANDD.SYS

NOTE: By Jeff Summer: Looking at the driver, it supplies the driver names \dev\LANDD$ and requires another device, \dev\protman$ to work. In my experience, in OS/2 it is strictly used for SNA, be that Anynet (NetBIOS over SNA/APPN) or simple Mainframe connectivity. It is also used to configure Bridges and LAM/CAU equipment. It does allow for some pretty cool stuff, like simple Token Ring utilization figures (a la Ringutil, IBM EWS, useless at full duplex, though) and Token-Ring Diags (last ring code, upstream neighbour, beaconing MAC, Ring Parameter Server reporting.)
